The theory behind stars twinkling is that: A) The refractive index of the different layers of earth's atmosphere changes continuously, consequently the position of the star's image changes with time B) The intensity of light emitted by them changes with time C) The light from the star is scattered by the dust particles and air molecules in the earth's atmosphere D) The distance of the stars from the earth changes with time
